They say that nudity is not inherently sexual. They say that we're not animals, that we can control ourselves even when seeing an attractive man or woman, even when seeing them naked.
We're not animals, except in the strict biological sense. We conceptualize sex. We imagine it, anticipate it, express our need and desire for it to ourselves and others. We're the only animals that have sex recreationally. Animals spend their whole lives nude, but they can't conceptualize mating. They only respond to environmental cues, pheromones, and displays both tactile and visual. A nude fellow animal means nothing to them. Mating means nothing for them.
When we see nudity, we imagine sex. A sight, a smell, a bare idea or random thought can be enough to arouse us, even in the absence of any concrete stimulus. Words alone can do it. A story or pixels on a screen can arouse us as surely as pheromones and displays and touch. We experience meaning in everything, and sex has meaning for us long before it ever has reality for us. Even before we understand fully what it is, it means something.
"Don't forget bonobos" Ally said. Her face rested on her fist inches from mine.
"What about them?"
"They have recreational sex."
I sighed. "OK, the exception that proves the rule."
"So it's because we're human that some of us get turned on at the first peek of bare skin?" Ally was thinking hard. She was very good at it. Finally, she said, "That same ability means we can deal with it appropriately."
"Of course we can." I said. "But if you're relying on not reacting to it, doesn't that concede that it affects us, that there is something not to act inappropriately on?"
She smiled, and wiggled her hips against mine. "I was counting on you not catching that."
We had met in Philosophy 101, about a year and a half ago when we were both college juniors. She was double majoring in English Lit and Anthropology of all things. It was a bizarre and ambitious combination, but, to my great luck, philosophy was a recommended elective.
To her great luck, it was a required elective for my AI major.
We were both naturally 'philosophical' types, and our conversations tended to go deep, not always in the sense of 'profound', but in the sense of getting at what was underneath things. The how, the why, beyond the who and the what.
Our conversations often went that direction even in bed, even when we barely had any clothes on, or no clothes on. Even, like now, when Ally was straddling my hips and pressing her bare pussy against my cock.
This argument about nudism, prompted by her discovery of a new holiday called "National Nude Day" was typical of how we were together.
"You knew I would," I said. "even with you doing your best to distract me." I pushed my hips up against her. I was still wearing the boxer shorts I usually slept in. She was wearing a tshirt that barely reached the bottom of her hips and nothing else.
We'd slept in, past 7 am, and were in no hurry to get up. We had nothing really to do today, despite both of us having generally busy work schedules. This kind of discussion was often part of foreplay for us, and we'd been together long enough to not feel any need to rush it. We would make love this morning, but we were in no hurry.
"So you don't think people can be nude around each other without getting turned on? Without thinking that sex is on the table."
"On the table, on the floor, on the bed, wherever. But yeah, you put a bunch of naked people in a room, people are going to get ideas."
"Sure", she countered, "but that's just our culture. Nudity itself doesn't do it, except when nudity is itself a deliberate action."
"What do you mean an action?"
She lifted her upper body and sat on my hips. She looked me in the eye and lifted her shirt, drawing her hands seductively over her breasts. It was just a quick flash, then she was laying on me again with her shirt pulled back down. I reacted exactly as she predicted.
"That erection you have, is that because you saw my tits, or because of how I showed them to you?"
"What's the difference?"
"If I was just nude, just talking, you'd be seeing my tits the whole time. Would that automatically get you turned on? Or was it because what I did was sending you a signal that I was trying to turn you on?"
While I thought about it, she reached down between us and worked my cock out from my boxers. She lined herself up and pushed back onto it.
"Now that was an overt act." I said.
She smiled. "It was, but by then you were already turned on. And so am I."
"Yeah. You're right, I guess. That that little display did it. And no, I don't get hard every time I see your tits, but my god, have you ever seen them? They're absolutely perfect."
"So you've said. I believe you." She wriggled her hips again, pushing me deeper inside her. That overt act got me thinking less philosophically and more carnally. But we just lay there enjoying the feeling of being joined, of being as close as two people can get.
We continued the argument. She insisted that the connection between nudity and sex was cultural. I argued that the human brain was hard wired by evolution to respond to certain patterns, like she shape of a body, hips, tits, chest and shoulders. It was a response that predated culture, that itself shaped culture.
Before we could settle it, there was a knock at the door. "You guys decent?" Ally's sister had just turned 18 a few months ago.
"What do you want, Sian?" Ally yelled over her shoulder. The door opened and all three of us realized what the situation was at the same time.
Sian froze for a second, standing half in and half outside the door. She gasped and covered her mouth with her hand.
Our conversation had been so natural, so typical, that we had lost track of how exposed we were.
Ally's eyes went wide, then relaxed. She stifled a laugh. We both looked back toward the door.
"Jesus you guys!" Sian said. She had not hurriedly backed out of the room, but just stood there, staring at us. "You said you were decent!" she demanded, finally looking at our faces.
"I didn't" Ally said. "I just asked what you wanted."
Sian looked at us like we were pedantic idiots. I couldn't deny it. I said, "Besides, what's indecent about it?"
"I walk into a room and the only thing I can see is my sister's asshole and her boyfriend balls buried in the crack of her ass." Sian said, as if it was self explanatory.
"Yeah, so?" I asked.
Sian just gave an exasperated sigh. "Mom and Dad want to know if you guys want to get waffles."
I brightened up. "Kenney's?" I asked. Kenney's was a local joint famous for their waffles. They had every variety you could think of.... no, every variety they could think of, and they were very creative.
I looked at Ally. Her enthusiasm was evident on her face. We had a short, silent conversation of facial expressions that settled the issue. "We're there" I said. Ally moved off me, forgetting, or not caring, that it exposed me fully to her sister.
"Just give us time for a shower." Ally said, moving to stand next to the bed.
That left me laying there with an erection propped up by the elastic waistband of my shorts. Sian just stared.
There was nothing for it, so I peeled them off in one smooth motion as I swung my feet off the bed and stood. Sian kept staring as I stood next to her with my penis pointing straight at her.
"Get your own dick." Ally told her, pretending to be mad. Sian had been a cheerleader in high school, having only graduated this spring. I had often fantasized about cheerleaders staring at my dick with a look of awe and longing. Sian's expression was not quite that, but if I squinted, I could pretend it was.
Ally peeled off her shirt.
